1 Suppression of CYP1A1 expression by naringenin in murine Hepa-1c1c7 cells. naringenin cytochrome P450, family 1, subfamily a, polypeptide 1 Mus musculus
2 In the present study, we investigated the effect of naringenin on 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)-inducible CYP1A1 gene expression in mouse hepatoma Hepa-1c1c7 cells. naringenin cytochrome P450, family 1, subfamily a, polypeptide 1 Mus musculus
3 TCDD-induced CYP1A1 mRNA level was also markedly suppressed by naringenin. naringenin cytochrome P450, family 1, subfamily a, polypeptide 1 Mus musculus
4 A transient transfection assay using dioxin-response element (DRE)-linked luciferase and electrophoretic mobility shift assay revealed that naringenin reduced transformation of the aryl hydrocarbons receptor(AhR) to a form capable of specifically binding to the DRE sequence in the promoter of the CYP1A1 gene. naringenin aryl-hydrocarbon receptor Mus musculus
5 A transient transfection assay using dioxin-response element (DRE)-linked luciferase and electrophoretic mobility shift assay revealed that naringenin reduced transformation of the aryl hydrocarbons receptor(AhR) to a form capable of specifically binding to the DRE sequence in the promoter of the CYP1A1 gene. naringenin cytochrome P450, family 1, subfamily a, polypeptide 1 Mus musculus
6 These results suggest the down regulation of the CYP1A1 gene expression by either naringenin in Hepa-1c1c7 cells might be antagonism of the DRE binding potential of nuclear AhR. naringenin cytochrome P450, family 1, subfamily a, polypeptide 1 Mus musculus
7 These results suggest the down regulation of the CYP1A1 gene expression by either naringenin in Hepa-1c1c7 cells might be antagonism of the DRE binding potential of nuclear AhR. naringenin aryl-hydrocarbon receptor Mus musculus
